BENDING=MACHINE SPECIFICATION forming part of Letters I atent No.603,926, dated May 10, 1898. Application filed November 2 6 1 8 9 7.Serial No. 6 5 9,8 5 '7. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES SEYMOUR, of Defiance, in the county ofDefiance and State of Ohio, have invented a new and ImprovedBending-Machine, of which the following is a full, clear, and exactdescription.

The invention relates to machines for bending timber used in carriageand wagon fellies, wagon-hounds, sleigh-runners, ham es, chairs, andother articles using bent-wood stock.

The object of the invention is to provide a new and improvedbending-machine which is simple and durable in construction, not liableto get out of order, easily manipulated, and arranged to insure a closeWrapping of the timber around the form without fracturing the timber byundue tensile strain.

The invention consists of novel features and parts and combinations ofthe same, as hereinafter more fully described.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of the improvement. Fig. 2 is a sectionalplan view of the same on the line 2 2 of Fig. 1, and Fig. 3 is a sideelevation of the same.

The bending-machine is provided with arms A A for forcing up the ends ofthe timber, the said arms extending normally in a horizontal position,as shown in Fig. 1, and having a master-strap B, of steel, or likematerial, extending over the said arms, which latter also supportadjustable head-blocks 0, against which abut the ends of the timberplaced on the top of the strap B. The outer ends of the arms A A areconnected with ropes, cables, or chains D, which extend upwardly andinwardly to pass over pulleys E, journaled in the upper end of standardsF, erected on the main frarneF of the machine. The ropes, cables, orchains D then wind on a drum G, journaled in the said standards,

as plainly indicated in Fig. 3, and driven by a suitable mechanism-such,for instance, as shown in the bending-machine covered by the LettersPatent of the United States N0.

497,060, granted to me on May 9, 1893, so that yieldingly-sustained wayfor the pulleys A further description of such driving device is notdeemed necessary.

The inner or adjacent ends of the arms A A are provided on oppositesides with grooved pulleys A A respectively, adapted to form thefulcrums for the said arms when the latter are swung upward upon windingup the ropes, cables, or chains D on the drum G. The pulleys A A on eachside of the arms A A are adapted to bear on a rope or cable 11,extending longitudinally and passing overgrooved pulleys I I, journaledin suitable bearings 1 adjustably held on inclined guiideways F formedon the main frame F under the arms A A, respectively. Each cable H afterleaving the pulleys I 1 passes around pulleys J J, journaled on theouter ends of the guideways F to then pass inwardly and connect withheavy helical springs K K, attached at their inner adjacent ends onsuitable brackets F forming part of the main frame F. The springs K Kexert such stress on the ends of the cables II that the inner ends ofthe arms A A are pressed in an upward direction, and it is evident thatwhen the arms A A are swung upward, as previously explained, then thesaid pulleys A A form the fulcrums for the arms and travel on thespring-pressed and yieldinglymounted cables H to insure a close wrappingof the 80 timber around the frame L, carried by the standard F, in theusual manner.

It will be seen that by the arrangement described the yieldingly-mountedand springpressed cables or ropes form an elastic or V A to travel onand at the same time exert such thrust against the pulleys, andconsequently against the upwardly-swinging arms A A, as to insure aclose wrapping of the timber bent by the arms around the form L. Whenthe timber has been bent around the form L, it is secured in bent shapeby suitable straps or shackles to permit ofretnrning the arms A A. totheir normal lowermost positionlshown in Fig. 1) to allow ofconveniently removing the bent timber from the form and to proceed tobend a new batch of timber in the manner above described.

The outer ends of the arms A A are provided with suitable feet A Arespectively,

adapted to rest on the floor to hold the arms normally in a horizontalposition, as indicated in said Fig. 1.

In the claims the expression rope is used in its broadsignificance-which is to say, as meaning any flexible connection orligament, such as a chain, thong, braid, &c.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a bending apparatus the combination of amain frame or bed, standards mounted thereon, a form carried on thestandards, two bending-arms located below the form, means in connectionwith the outer ends of said arms to swing the same, a master-strapextending from one arm to the other, a rope run below the arms, pulleyson which the rope is carried, a spring respectively in connection withthe ends of the rope and serving to hold the rope taut, the rope forminga support for the inner ends of the arms and serving to thrust the armstoward the form.

2. In a bending apparatus the combination of a frame, a form supportedon the frame, two bending-arms mounted below the form, a master-strapextending from one'arm to the other, means for swinging the arms, a roperun beneath the arms, pulleys over which the rope is rolled, the pulleysbeing carried by the frame, and springs serving to draw the rope tautbeneath the arms, the rope forming a yielding support for the inner endsof the arms and serving to thrust the arms toward the form.

3. In a bending apparatus the combination with a frame, of a form, twobending-arms mounted below the form, means for swinging said arms, and ayieldingly-sustained rope run below the arms and serving to support theinner ends thereof and to thrust the arms toward the form.

4. In a bending apparatus the combination I of a form, two bending-armsin line with each other and having contiguous ends, means for swingingthe arms, and a yieldingly-sustained rope run beneath the arms andforming a support for the inner ends thereof, and serving to thrust thearms toward the form.

5. In a bending apparatus the combination with a frame, of twobending-arms mounted thereon, the arms being in line with each other andhaving contiguous inner ends, means for swinging the arms, and ayieldingly-su'stained rope run beneath the inner ends of the arms andserving to yieldingly support the same.

6. In a bending apparatus the combination of a frame, two bending-arm'sin line with each other and having their inner ends contiguous, meansattached to the outer end of each arm by which to move the same, and ayieldingly-sustained rope run beneath the inner ends of the arms andserving to yieldingly support the arms.

7. In a bending apparatus the combination of a form, two bending-arms inline with each other, and having their inner ends contiguous, amaster-strap running along the arms and connected with each meansattached to the outer end of each arm, by which to move the arms, and ayieldingly-sustained rope run in proximity with the inner ends of thearms and serving to support the arms and to thrust the arms toward theform.

8. In a bending apparatus the combination of a form, bending devicesmounted adjacent to the form and coacting therewith, and ayieldingly-sustained rope serving to support said bending devices and tothrust them toward the form.

9. In a bending apparatus the combination of bending devices, and a ropeyieldingly sustained in proximity with the bending devices and servingto support the same.

10. Inabendingapparatus the combination with a frame having standardsthereon, of a form held by the standards, two bending-arms in line wit-heach other and having their inner ends contiguous, the bending-armsbeing mounted on the frame below the form, means for lifting thebending-arms, such means being attached to the outer ends thereof, and ayieldingly-sustained rope run beneath the inner ends of the bending-armsand serving to support the same and to thrust the arms toward the form.
